Dr. Rajesh Koothrappali is definitely a faculty and astrophysicist user in Caltech’s Physics Department. He had been an element of the group to develop the newest Horizons area probe to get information in regards to the Pluto system and past. For their development of a object that is planetary the Kuiper gear, 2008 NQ17 ( that he calls “Planet Bollywood”), he’s incorporated into individuals mag’s “30 Under 30 to Watch”, granting him some type of celebrity status and a more substantial workplace for their work.
